Questions owners ask first.

“I'm not technical.”
You don't need to be. I set up the AI assistant and teach your team the parts they use.
“We already pay for ChatGPT.”
Keep your plan. Your AI assistant uses the same models, connected to your own tools.
“What if something breaks?”
I watch your AI assistants and fix what breaks. Your team learns the basics too, so small fixes take minutes.
“Will this replace my people?”
Your team stays. Your people are freed up for the important work.

I run Praxis on the same AI assistants I set up for you.

My career in tech started in visual effects in 1996. Then I ran Bauhaus, a design-build firm, for over 15 years.

That's where my obsession with inefficiency started, and with finding better and faster ways.

Interior design, architecture and construction are ridiculously inefficient. Bauhaus became one of the first firms in Dallas to give every client a photorealistic 3D design, built in Unreal Engine.

The deep insight into those inefficiencies led to my next company, VIRTUALhaus, which I founded in 2018 and which raised a $2.6M seed round backed by Builders FirstSource, one of the nation's largest building materials distributors. VIRTUALhaus was a marketplace and estimating platform for building products. The goal was to make estimating, budgeting and buying for construction projects faster and more efficient.

My first work with AI came at VIRTUALhaus in 2020, two years before ChatGPT. I took an MIT course on AI, then went deep on AI image and video models. When ChatGPT launched, I watched it turn hours of project documents into a structured request for quote.

I realized then that AI would ignite a fundamental transformation of how businesses operate and sell products.

I started Praxis to help people and businesses change how they work with AI assistants, and to teach people to get fluent with AI, so they can rethink how they work and run their business.

Today an AI assistant writes my morning briefing before I start, and I set up the same kind for owners like you.

Three things to try today.

Free, no sign-up.

  1. 01Ask why before you ask for a fix.When Claude gets something wrong, ask Claude to explain the mistake first. The fix that follows is better.
  2. 02Number your folders.Start folder names with a number so they sort the way you think. Claude finds them the same way.
  3. 03Share one folder, not your whole drive.Claude only sees the folders you share. That guardrail always holds.

One new way to use AI, every week.

The Company Builder's Manual. Free. A 5-minute read.
